Correct answer
A. Average bond enthalpy is the energy required to break a specific type of bond in a molecule, while the differe
Step-by-step solution
Correct Option is : (A) Average bond enthalpy is the energy required to break a specific type of bond in a molecule, while the difference in O—H bond enthalpy is due to the presence of different chemical environments in ethanol and water.
